Due to the excellent anticonvulsant activity of previously synthesized halogenated enaminones, more disubstitutedanalogs were synthesized and evaluated in vitro. The new enaminones either had no effect, depressed, or enhanced population spike (PS) amplitude in the rat hippocampus in a concentration-dependent manner. Structure–activity relationship (SAR) analysis indicated that compounds 21 and 25

The enaminone esters provided nucleophilic and electrophilic sites for a variety of reactions. Thus, the enaminone esters were converted into enaminone amides and O-alkylation products exclusively. Although the enaminone esters were generally resistant to reduction by metal hydrides, one unhindered enaminone ester was reduced to an alcohol with sodium borohydride. Another enaminone ester reacted with
Discovery of novel antibacterialagents with new structural scaffolds that combat drug-resistant pathogens is an urgent task. Cajaninstilbene acid, which is isolated from pigeonpea leaves, has shown antibacterial activity. In this study, a series of cajaninstilbene acidderivatives were designed and synthesized. The antibacterial activities of these compounds against gram-negative and gram-positive
